[yt-users] x-velocity

[Jean-Claude Passy]

Hi all,

there is something regarding the x-velocity field I don't really understand.

When I analyze a file with yt, I find:

######################################################################
In [1]: filen = 'DD0001/CommonEnvelope0001'


In [2]: pf = load(filen)


In [3]: region = pf.h.region([0.5, 0.5, 0.5], [0.0, 0.0, 0.0], [1.0,1.0, 
1.0])

yt INFO 2010-08-08 14:29:57,375 Getting the binary hierarchy

yt INFO 2010-08-08 14:29:57,389 Finished with binary hierarchy reading


In [4]: vx = region["x-velocity"]

yt INFO 2010-08-08 14:30:06,647 Getting field x-velocity from 1


In [5]: max(vx)

Out[5]: 232812.74801568719

######################################################################

with the latest results being in cm.s-1
However, when I make a slice and plot the x-velocity field, I end up 
with the figure enclosed, saying that the max velocity is around 1.6e-4 
cm.s-1 !

I don't quite understand. Where am I wrong ?
Thanks for yoru help,

JC
